Under certain circumstances, not every message written by the MCU to the status mailbox may trigger a corresponding interrupt. This is likely when multiple messages are generated in a very short period of time. Since the current implementation only processes one message per interrupt, even if multiple messages are already available in the mailbox, expected messages are either not received or are processed late. This leads to various subsequent problems and causes the driver to no longer function properly. The behavior has been adjusted so that after an interrupt, all messages available in the mailbox are processed.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
